As defined in the ACPI spec section 12.11, ACPI hardware-reduced platforms define the EC SCI interrupt as a GpioInt in the _CRS object. This replaces the previous way of using a GPE for this interrupt; GPE blocks are not available on reduced hardware platforms. Add support for handling this interrupt as an EC event source, and avoid GPE usage on reduced hardware platforms. This enables the use of several media keys (e.g. screen brightness up/down) on Asus UX434DA. Signed-off-by: Daniel Drake <drake@endlessm.com> Signed-off-by: Rafael J.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
